Hi all,


I have an issue of duplicated metric from snmp_exporter for this OID

ltmVirtualServStatClientCurConns | 1.3.6.1.4.1.3375.2.2.10.2.3.1.12 from 
F5-BIGIP-LOCAL-MIB
http://www.oidview.com/mibs/3375/F5-BIGIP-LOCAL-MIB.html


When i check the /metrics output from snmp_exporter for that target i can 
see this error.

collected metric "ltmVirtualServStatClientCurConns" { 
label:<name:"ltmVirtualServStatName" 
value:"/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2app.pri"
 > counter:<value:0 > } was collected before with the same name and label values


I should have two different metrics with two different 
"ltmVirtualServStatName" label value below:

/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2app.private.sfr.com_HTTP_extra
/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2app.private.sfr.com_HTTP_intra

but it seems that the "ltmVirtualServStatName" label_value is limited to 
"/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2app.pri"
 
in the /metric output so the snmp_exporter is seeing the same metric two 
times and drop the error.


I have another F5 LTM in the cluster with the same configuration (but 
another version) and i can get two different metrics

ltmVirtualServStatClientCurConns{ltmVirtualServStatName="/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2a780a7faf"}
 0
ltmVirtualServStatClientCurConns{ltmVirtualServStatName="/Common/ref-si-silo-cs-pdct-rp2web2app.private.sfr.com.app/vip-ref-si-silo-cs-pdct-rp2web2ac8889aed"}
 0

This time it seems that the snmp_exporter is putting a random string at the 
end of the label ltmVirtualServStatName to make it unique

Do you have any idea why this is happening ? The MIB is the same on both 
devices.

Thanks!

Flo
